Interbedded shale, quartzite, and dolomite in the upper part of the Wood Canyon Formation in the ridge along the north side of Blackwater Wash.Circa 1960. This formation is composed of angular fragments of many different kinds of parent rock, and it can be seen on the floor of the canyon just south of the parking area. This inference is based on a compilation of age data for the Death Valley region, combined with a new interpretation of the geometry of detachment surfaces. As also discussed earlier, the Panamint Range is a large, almost symmetric anticlinal structure, with no high-angle faults along the western side of the range. They are made up of Proterozoic basement gneiss, early Tertiary pegmatitic intrusives, and Late Miocene plutonic rocks. Smoky Member is light-to dark-gray cliff-forming dolomite, dark-gray to light gray; mottled, medium crystalline and thin to thick-bedded, discontinuous layers and nodules of dark-brown weathering chert.

Stratigraphic nomenclature for the Proterozoic and Early Paleozoic section of the Death Valley area. It has a width of about 10 miles (16km). Labels are colored for visibility only. The middle member is characterized by the brachiopods Cyrtospirifer, and Stringocephalus, the stromatoporoids Amphipora and Stromatopora, and cladoporoid corals. [7] As sand moves down the dune face it produces a booming noise, known as singing sand phenomenon, due to the small grain size and loose, dry packing. 6) is an antiformal structure formed by arching of the exposed detachment surface; I suggest that this arching also forms the rest of the Panamint Range, making the entire range a core complex. Deposition of these formations initiated near the end of events associated with Basin and Range extension, starting with the predominantly volcanic Artist Drive Formation (Greene, 1997). The Late Miocene intrusives consist of the mafic Willow Springs pluton and the felsic Smith Mountain granite. At Lake Hill, the lower unit contains the cephalopod Armenoceras and several species of the brachiopod Lepidocyclus. They also lie on the flank of a Proterozoic rift basin filled with Pahrump Group sediments, as mapped by Wright et al. A 20 m thick white quartzite marks the base of the unit in the Specter Range and northwestern Spring Mountains. tubes. DATA AND EXPLANATIONS OF ABBREVIATIONS USED IN FIGURE 3, Jackson School of Geosciences, Institute for Geophysics, University of Texas at Austin, J.J. Pickle Research Campus, Bldg. Unit is about 345 to 380 m thick in the Spring Mountains and southern Sheep Range, 365 m thick in the northern Last Chance Range, 457 m in the Panamint Range area, about 530 m thick in the Nopah Range and in the Cottonwood Mountains, 766 m thick in the Pahranagat Range, 720 m thick in the NTS area. b. The wetland lies at the southern tip of the Ibex Hills, on the floor of Death Valley and just northeast of the Amargosa River. Contains basalt, alluvial and lacustrine deposits and vertebrate trace fossils in the lacustrine strata (e.g. These sediments are younger than the Copper Canyon Formation, with the 0.77 Ma Bishop tuff (number 3 in Fig. From Dante's View one can see the central part of Death Valley from a vantage point 5,500 feet (1,700m) above sea level. The Walker Lane belt was originally defined by Stewart (1988) as the triangular zone of high topographic relief separating the Sierra Nevada from the Great Basin, with its southern limit the Garlock fault. Pennsylvanian In some areas all that remains of some thick rock layers are lens-shaped pods of rock bounded on all sides by faults. Ventifact Ridge is a part of a basaltic lava flow. 7 Warm Spring Granite At Mosaic Canyon, for instance, where the detachment surface is exposed (TD, Fig. 14 Skidoo Granite 6). Varnish does not normally form on carbonate rocks because their surfaces weather too easily. The dip of the steeper portion of the west side of the basin is 30, and the surface projection of this portion is close to faults at the base of the alluvial fans on the west side of Death Valley (Hunt and Mabey, 1966; USGS Quaternary faults database), again suggesting that the basin is fault-bounded, as shown in Figure 9. Saratoga Springs (.mw-parser-output .geo-default,.mw-parser-output .geo-dms,.mw-parser-output .geo-dec{display:inline}.mw-parser-output .geo-nondefault,.mw-parser-output .geo-multi-punct{display:none}.mw-parser-output .longitude,.mw-parser-output .latitude{white-space:nowrap}354054N 1162525W / 35.68167N 116.42361W / 35.68167; -116.42361[11]) is a desert oasis located in southern Death Valley National Park. Stromatoporoids. This implies that there should be a detachment fault underneath the Panamint Range. a. Dips of the flanks of the Panamint Range are shallow, averaging 10. Further south, a strike-slip fault has been mapped by Zhang et al. / i) (d vli) (Tal des Todes) liegt in der Mojave-Wste und ist der trockenste Nationalpark in den USA.Er liegt sdstlich der Sierra Nevada, zum grten Teil auf dem Gebiet Kaliforniens und zu einem kleineren Teil in Nevada.Die Region ist ein Hitzepol.. Der tiefste Punkt des Tales liegt 85,95 Meter unter dem Meeresspiegel und ist zugleich . Schematic evolution of the cross section of Figure 9. 37 Noonday Dolomite c. Widely exposed in map area. Widely distributed fusilinids. Polished marble, chiseled dolomite, and the canyon's namesake mosaic-like fragment formations . Prior to this time, a thick sedimentary sequence was deposited in what is now the northern Black Mountains, with early sedimentation being mostly volcanics. Trends in oolite dolomitization across the - ScienceDirect 9 Furnace Creek Formation Thickness, 1,500 feet. Basin and Range extensional allochthons occur along the east flank of the range; these formed during MioceneEarly Pliocene Basin and Range extension. Ash layers, important for age control on sediments, are included in the igneous activity column, although the volcanism that produced these ash beds was usually well outside the Death Valley area (Knott et al., 2005). Hornblende quartz monzonite with variations. Following a right-hand bend and broader left turn, the canyon further constricts at 1.25 miles, forming orange- and gray-tinted narrows. Miller and Pavlis (2005) divided these models into two categories, depending on how strike-slip and low-angle detachment faulting are combined. Dips of the Paleozoic strata at the eastern end of the section are from Hunt and Mabey (1966), as is the location of the detachment below these strata; Figure 7 is a summary of stratigraphic nomenclature for these older sediments. Also in this area, McKenna and Hodges (1990) mapped the 8.69.4 Ma Trail Canyon volcanic sequence (Fig. No fossils. In this new interpretation, a detachment surface tracks over the crest of the Panamint Range, rather than underneath the range, and the Black Mountains turtlebacks are megamullion structures formed as a result of strike slip. (Blair and Raynolds, 1999); (4) although there are angular unconformities within these formations, there are no data such as progressive tilt (Snow and Lux, 1999) to suggest that they were deposited in active grabens. is a cherty argillaceous unit containing Lower Devonian fish, the pteraspidids Blieckaspis and Panamintaspis from the Trail Canyon area. The falls themselves support several small fern gullys. The rock unit being folded is the Noonday Dolomite, a Neoproterozoic carbonate unit that exhibits gorgeous ductile deformation in Mosaic Canyon. Thickness of Cenozoic sediments from the digital compilation of Blakely and Ponce (2002) in color. Also not consistent with this model is the fact that the Panamint Range is much higher in elevation (highest point is Telescope Peak, 3368 m) than the Black Mountains (highest point is Funeral Peak, 1946 m); this would mean that the hanging wall of the detachment would be higher than the footwall, a structurally unlikely scenario. 18 Owens Valley Formation The other period of interruption occurred between 350 and 250 Ma when sporadic pulses of mud swept southward into the Death Valley region during the erosion of highlands in north-central Nevada. b. *9 Members* alternating siliciclastic and carbonate facies lower four (of the nine) members and the lower part of the fifth member contain Early Cambrian olenellid trilobites. In Wildrose Canyon, unit contains abundant microcline, and dominant rock type is granite. a. Interbedded fluvial and marine sequences fine-grained, cross-stratified, locally conglomeratic sandstone, intervals of siltstone and carbonate rocks in the Funeral Mnts. No fossils. a. At the junction where the unimproved road from Ubehebe Crater meets roads to the Racetrack Playa and Hunter Mountain (364537N 1173233W / 36.76028N 117.54250W / 36.76028; -117.54250), there is a sign reading "Teakettle Junction. Blakely et al. Death Valley National Park is one of many units within the National Park service established because of its underlying geologic theme. (1990) along the west side of the range, but the dip of this fault is not known. The main visitor center of the park is located here as well as the Oasis at Death Valley resort complex. (2000). camel, horse, bird, carnivore). Death Valley is a playground for geology enthusiasts, maybe even more like a Mecca. Consists of conglomerates, sandstones, calcareous mudstones, algal limestones, and tuffaceous sandstones, fossil mammals include Protitanops, Mesohippus, Colodon, Teletaceras, Protoreodon, Pambromylus, and Leptomeryx found in red calcareous mudstone in the lower section of this formation. This cross section, like Figure 6, uses topographic data from the DEM and outcrop geology from Workman et al. Check out the dolomite promontory that gave mosaic Canyon its name, too! [17], The rock at the junction includes the bedrock sandstone of the Eureka Quartzite strata.[18]. The west side of the basin shows a steep segment bordering the main basin and a gently dipping surface that joins to the Panamint Range. Rocks now in the crest of the range were metamorphosed to greenschist facies, representing 10 km burial, in the Jurassic, with retrograde metamorphism associated with granitic intrusions in the Cretaceous (Labotka and Albee, 1990).
